Your brakes are the single most important safety system on your vehicle. They are responsible for bringing your car to a safe and controlled stop, and they need to be in top working order at all times. While brake pads often take center stage in discussions about brake maintenance, the rear brake shoes play a crucial role as well. Over time, brake shoes can wear down, become contaminated, or simply lose their effectiveness. Knowing how to remove and inspect your rear brake shoes is an essential skill for any car owner who wants to keep their vehicle safe and reliable.

Understanding Rear Brake Shoes
Unlike brake pads, which are typically found on disc brakes, brake shoes are used in drum brakes. Drum brakes consist of a rotating drum that houses the brake shoes. When the brake pedal is pressed, hydraulic pressure forces the brake shoes against the inside of the drum, creating friction that slows the rotation of the wheel. This friction converts kinetic energy into heat, ultimately bringing the vehicle to a stop.
Components of a Drum Brake System
- Brake Drum: The cylindrical metal housing that contains the brake shoes.
- Brake Shoes: The friction material-lined pads that press against the inside of the drum to create braking force.
- Brake Cylinders: Hydraulic cylinders that apply pressure to the brake shoes.
- Adjusting Mechanism: A system that automatically or manually adjusts the clearance between the brake shoes and the drum to ensure proper braking performance.
- Wheel Cylinders: Hydraulic cylinders that press the brake shoes against the drum.
Signs of Worn Brake Shoes
It’s important to regularly inspect your rear brake shoes for signs of wear and tear. Some common indicators include:
- Squealing or grinding noises when braking.
- Reduced braking effectiveness.
- Dragging brakes.
- A burning smell when braking.
Tools and Safety Precautions
Before you begin removing your rear brake shoes, gather the necessary tools and take the appropriate safety precautions:
Tools Required
- Socket set
- Wrench set
- Breaker bar
- C-clamp
- Pry bar
- Hammer
- Jack and jack stands
- Gloves
- Safety glasses
Safety Precautions
- Always work on a level surface with the parking brake engaged.
- Never work under a vehicle supported only by a jack. Use jack stands for added safety.
- Wear gloves and safety glasses to protect your hands and eyes from debris.
- Be aware of hot brake components. Allow the brakes to cool completely before working on them.
Step-by-Step Guide to Removing Rear Brake Shoes
Now that you’re prepared, let’s walk through the process of removing your rear brake shoes:
1. Prepare the Vehicle
Park your vehicle on a level surface and engage the parking brake. Chock the front wheels to prevent the vehicle from rolling. If necessary, disconnect the negative battery terminal to avoid accidental electrical shorts.
2. Remove the Wheel
Using a lug wrench, loosen the lug nuts on the rear wheel you’ll be working on. Once loosened, jack up the vehicle and secure it on jack stands. Remove the lug nuts completely and take off the wheel. (See Also: How to Remove Air from Brake Lines Without Bleeding? Simplified Solution)
3. Access the Brake Drum
Locate the brake drum retaining clips or bolts and remove them. The brake drum may be held in place by a snap ring or other retaining mechanism. Carefully remove the drum, taking note of its position and any shims or spacers.
4. Inspect the Brake Shoes
With the drum removed, you can now inspect the brake shoes. Look for signs of wear, cracks, or glazing. Also, check the condition of the brake cylinder seals and adjusters.
5. Remove the Brake Shoes
The brake shoes are typically held in place by springs and clips. Carefully remove these springs and clips to release the shoes from the backing plate. You may need to use a pry bar or hammer to gently persuade the shoes free if they are stuck.
6. Clean and Inspect the Backing Plate
Once the brake shoes are removed, clean the backing plate thoroughly to remove any dirt, grease, or debris. Inspect the backing plate for any signs of damage or corrosion.
7. Reassemble the Brakes
When reinstalling the brake shoes, ensure that they are properly seated and secured with the springs and clips. Reinstall the brake drum and secure it with the retaining clips or bolts. Do not overtighten the fasteners.
8. Adjust the Brakes
After reassembling the brakes, adjust the brake shoes to the correct clearance. This typically involves turning a star wheel or adjusting screw located on the brake backing plate. Refer to your vehicle’s repair manual for specific adjustment procedures. (See Also: How Much Are Brake Pads and Discs? The Ultimate Cost Guide)
9. Test the Brakes
Before driving, test the brakes carefully in a safe area. Apply the brakes gradually and listen for any unusual noises or feel for any vibrations. If everything feels normal, you can drive your vehicle with confidence.
